Vladimir79 [104]3 years ago
3 0

Step-by-step explanation:

3x + 2y = 9

- (3x + y = 6)

=> y = 3.

Therefore 3x + (3) = 6, 3x = 3, x = 1.

The solutions are x = 1 and y = 3.

Which equation can be used to find the area of the of the trapezoid?
Leto [7]

Answer:

C) 1/2(15 +23)(9)

Step-by-step explanation:

The formula for the area of a trapezoid in terms of base lengths b1 and b2 and height h is ...

... A = 1/2(b1 +b2)h

Substituting the values shown in the figure, this becomes ...

... A = 1/2(15 +23)(9) . . . . . matches selection C

The function g(t)=−16t2+vt+h represents the height of an object, g, in feet, above the ground in relation to the time, t, in sec
kow [346]

Answer:

A) g(t) = - 16*t² + 80*t

B) domain is  ( 0 ≤ t ≤ 5 )

Step-by-step explanation:

A) for the model rocket

h = 0    and  v = 80 feet/sec

Then the equation     g(t)  = -16*t² + v*t + h

became

g(t) = - 16*t² + 80*t + 0         g(t) = - 16*t² + 80*t

B) The equation  g(t) = - 16*t² + 80*t  is defined for all real numbers then the domain interval for t is ( -∞ , ∞ ). Now in our case, a model rocket was launched is not possible to get negative values for g(t)  then the biggest value for t = 5 from

-16*t²  +  80*t  ≥ 0

-16*t  ≥ -80       16*t ≤ 80

t ≤ 5

And the domain is  ( 0 ≤ t ≤ 5 )
